The developer has created an app called Winky, which lets you power up Glass from standby and take a picture with just a single wink. There's even a video of the process in action. Clearly, a long deliberate wink is required—so as not to misinterpret blinking, presumably—but it's pretty neat that it's possible to command the device without touch or voice.
Indeed, DiGiovanni thinks that it "really changes things", and one suspects that it won't do much to help ease the privacy concerns surrounding Glass. But we'll be able to find out in real time, because DiGiovanni has made the source code for the app available on GitHub, so that early adopters will be able to take as many wink-triggered pictures as they like. Creep shots have never been so easy. [Google+ via Verge]
